player look in camera direction

Hi I have been looking to do the same sort of function!

I have had no luck in putting the above code into my current move script.

This is what I have at the moment

 private Vector3 moveDirection = Vector3.zero;
 public Vector3 MoveVector { get; set; }
 
 public void UpdateMotor() 
 {
     SnapAlignCharacterWithCamera();
 }
 
 void Update() 
 {
     CharacterController controller = GetComponent<CharacterController>();
     
     if (controller.isGrounded) 
     {
         moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
         moveDirection = transform.TransformDirection(moveDirection);
         moveDirection *= speed;
         
         if (Input.GetButton("Jump"))
             moveDirection.y = jumpSpeed;             
     }
     
     moveDirection.y -= gravity * Time.deltaTime;
     controller.Move(moveDirection * Time.deltaTime);
 }

}

Was wondering if I could get some help :D I'm a massive scripting noob :/

Thanks
